At one point, Lewandowski, who was standing to the left of a security guard, appears to reach between Trump and Fields with his left hand.

Trump's campaign on Thursday flatly denied that the incident involving Lewandowski and Fields had occurred, while the aide himself accused Fields of being an "attention seeker."

Turmp himself late Thursday night after the GOP debate denied that the incident took place, suggesting that Fields had made it up after she displayed bruising on her arms in an interview with ABC News.
